A regulating valve with multi-flow control

Abstract

The utility model discloses a regulating valve with multi-flow control, which relates to the field of fluid valves. The regulating valve with multi-flow control includes a valve seat and a spherical valve core installed inside the valve seat, a self-locking valve stem is installed on the top of the spherical valve core, and the spherical valve core includes a spherical valve core body, a water inlet groove, a through groove and a one-way valve plug. The regulating valve with multi-flow control rotates the handle bar toward the target water outlet pipe so that the through groove is directly opposite to the target water outlet pipe, and the water inlet groove is always connected to the water inlet pipe due to its large lateral opening. At this time, the water at the end of the water inlet pipe impacts the one-way valve plug, causing the one-way valve plug to slide away from the water inlet pipe. At this time, the water enters the through groove through the drainage hole and is then discharged through the water outlet pipe, thereby realizing the control of connecting multiple water outlet pipes with a single valve stem, which is simple to operate. At the same time, the one-way valve plug is used to prevent backflow, effectively prevent backflow, and has lower cost.

Description

Technical Field

[0001] The utility model relates to the technical field of fluid valves, in particular to a regulating valve for multi-flow direction control. Background Art

[0002] As a unit used for fluid control, fluid valves are usually installed on pipelines. Depending on their functional classification, they can be used to open and close fluid channels, switch flow directions, and control flow rates.

[0003] In a pipeline environment with single-pipe input and multiple-pipe output, a multi-way valve is usually required for control. The main principle is to install multiple joints on the input pipeline, install opening and closing valves on different joints, and connect different joints to different output pipelines at the same time to achieve multi-way control. However, when switching the flow direction of the pipeline, this type of design requires closing the valve on the original output pipeline first, and then opening the target pipeline valve. This is not only cumbersome to operate, but also has multiple control valve stems, resulting in high costs and high risks of failure. At the same time, after switching the pipeline, if the output pipeline pressure is high and there is backflow, a check valve needs to be additionally installed, further increasing the cost. For this reason, a multi-flow direction control regulating valve is specially provided to solve the above problems. Utility Model Content
